Digging more, loadfile("192.0.2.1::pxe.0", &file.data, &file.size), queries DNS, which sounds like it doesn't follow the same call path as a COM32 calling pxe_dns(). If the DNS won't resolve the IP, things won't load properly. pxechn.c32 sets sname in the intended packet to "192.0.2.1" which may be confusing something. More debugging needed. -- -Gene

From: Matt Fleming <matt.fleming at intel.com> The following patch series is available at, git://git.zytor.com/users/mfleming/syslinux.git elflink All patches are against the 'elflink' branch. This series fixes a few serious bugs and some behavioural incompatibilities with the 4.x series. Matt Fleming (19): ldlinux: Initialise 'p' before using it. ldlinux: Parse

From: Matt Fleming <matt.fleming at linux.intel.com> This series fixes some bugs and switches the elflink branch to be entirely ELF modules. It applies on top of, http://syslinux.zytor.com/archives/2011-April/016369.html The deletions in the diff stat below are mainly from deleting com32/elflink/modules (finally!). Now there should be no duplicate code because we don't need COM32 and
